I have been running a 5.7
I have been running a 5.7 crew cab long bed with headers and exhaust on 35"s with room for 37"s for over a decade (My chains are +3" diameter If run them). The new numbers don't impress me that much. I am one of the few that uses his truck like a truck though. Including offroading, hunting,camping and pulling a 20' boat to go fishing. I go out a few times a year in 5' plus snow. Aired down. Usually packing a few feet and riding on a few more feet. Daily commute of less than 20 miles. So I am not who Toyota builds trucks for. I didn't expect to be impressed until I read this would be a game ender for the truck markets. (Cough) really? Those numbers are good...but? On the lightest tundra with a supercharger they are putting down over 600hp to the tires..650 I think is where the transmission starts to let go.I think my mileage sucks but I actually almost match a big ford turbodiesel on 35"tires. So I'm not doing that bad really. Diesel has the most but per drop so for ultimate efficiency it's hard to beat one on the road off road an extra 800+ pounds in the front is not helpful to me. I know I don't get power without fuel consumption. Simple math..I would give up more mileage for more power. Give me a supercharged intercooled V8 with big rings in the pistons !!! With a straight axle in the front with lockers front and rear and get rid of the traction control that makes the truck dangerous. A real differential that doesn't use the brakes to (not) work properly. Terrible performance from the Toyota lotsa/slip differential..I would like 500hp 800 lb-ft for my towrig daily driver minimum. Premium gas. Your daily driver should excite you. I have plans for 1000/1000 in a 5k pound blazer. So again..I'm not the norm..why not a true long travel desert truck like other makes offer? Why not a straight axle or independent option on the same truck? Why not portal axles? Central tire inflation? Why not be able to plug your truck in at night if you want.? ..dual alternators, batteries moved to the bed. A brain to let you see your batteries and electrical systems better. Toyotas are always a trade off usually of something for reliability. I could tell you 10's of things I hate about the truck for my purposes. I accept those shortcomings for piece of mind. My wife might get one of the last new 5.7 Tundras. Or were building her a blazer. My next truck will be an older Chevy 3+3 on big tires (42") with a big block that should get around 6-8 mpg unloaded if I build it properly..
There was something to be said for my crew cab f350. I always knew I had enough truck for anything I was gonna hook up..I also knew if I ran it hard pulling trailers I would replace the transmission almost every year. Yup.
